MACHINE FOR WEAVING CANE-WORK.

SPECIFICATION forming part of Letters Patent No. 435,947, datedSeptember 9, 1890.

Application filed March 2, 1889. Serial No. 301,780. (No model.)

To all whom t may concern:

Be it known that I, FRANK F. PARKER, of Gardner, county of XVorcester,State of Massachusetts, have invented an Improvement in Machines forIVeaving Cane-VVork, of which the following description,l in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representinglike parts.

In the production of cane-work fabric for chair-seats and other purposesthe cane fabric, after its longitudinal or warp strands have beeninterwoven with the transverse or weft strands, is provided, bya handoperation, with a series of diagonal strands, which are passed over andunder the warp and weft strands, thus partially lling in the rectangularspaces or checks between the warp and weft strands.

My invention has for its object the production of a novel mechanism forintroducing these diagonal strands into cane fabric.

In my invention the cane fabric, while clamped between clamps or jaws,is subjected to the action of a series of projections both above andbelow the fabric, which projections, by acting upon the warp and weftstrands, push some of the said strands up and other of the said strandsdown alternately, thus forming, as it were, an unobstructed channeldiagonally across the fabric for the introduction of a cane, carried,preferably, by a carrier, (herein shown as a needle having a slot oreye, into which the end of the strand to be inserted in the diagonalpassage in the fabric is threaded 3) but I desire it to be understoodthat instead of the particular carrier herein shown I might employ anyother usual or well-known carrier-such, for instance, as commonly usedin looms for weaving haircloth. The carrier o-r needle having beenthrust diagonally through or across in the channel referred to, whichchannel is diagonal to the length of bothJ the warp and the weftthreads, the strand to be inserted is presented to the carrier, so thatas the carrier is retracted the strand-is drawn into the fabric, thestrand being cut oif just before or as the carrier 'completes itsreturn-stroke with the strand. The strand having been inserted is movedforward, taking with it the fabric a distance equal to one row ofchecks, and then the vclamp is opened, the upper and lower membersthereof are separated to disengage the fabric, and the clamp is movedbackwardly and again closed upon and so as to again clamp the fabric andform a channel therein for the strand. The feed-stroke of the clamp isfor a greater or less distance, that depending upon the size of thecheck. As herein represented, the strand is fed into the carrierautomatically by a threader (shown as a jaw) having a dog to act uponthe strand and insert the point thereof into the hole or eye in thecarrier or needle, or to present the strandto the carrier to be engagedby it, the strand being taken by the carrier from the threader; but thisstrand might be presented to the carrier by hand, although not soexpeditiously and economically. In practice the strand will be cut offnext the threader by a cutter just before the strand is fully drawn in.the strand just before the carrier completes its backward stroke, so asto enable the carrier to discharge the end of the strand, and thereafterthe cutter acts to sever the strand, the shape of the cutter being suchas to point the strand.

I have herein shown my invention as embodied in anautomaticallyoperating ma- The cutter will be so actuated as to holdchine, in which the fabric is lfed during the reciprocation in onedirection of the clamp described.

I do not desire to limit my invention to the exact shape and form ofclamp so long as the clamp operates as will be herein described.

My invention consists, essentially, in the combination, with areciprocating separable clamp to clamp the cane fabric andform adiagonal channel in the same, and means to reciprocate the clamp, of acarrier to insert a strand into the said channel, and means, asdescribed, to separat-e the clamp during its reciprocation in onedirection and to close it in its movement in the opposite direction,substantially as will be described; also, in the combination, with aclamp to clamp the cane fabric and form a diagonal channel, of a carrierto insert a strand in the said passage, and a threader to thread thesaid carrier; also, in the combination, with a clamp to IOO through thesaid passage, of a cutting device to sever the said strand to the properlength, 4substantially as will be described.

The frame-work A is and may be of suitable shape to sustain the workingparts. This frame-work contains suitable bearings for the cam-shaft A',having at one end a toothed gear A2, which is engaged by a pinion A3,fast on a power-shaft A4, having usual or suitable driving-pulleys to bedriven by power. The cam-shaft A has fast upon it a beveled gear a,which engages a beveled gear a', fast on a vertical shaft ax, having itsbearings in cross-bars a2 a2, the said shaft between the saidcross-bars, as herein shown, having fast upon it a cam, as a3, having,as herein shown, a groove, the shape of which is best shown in Fig. 8 ofthe drawings, the said groove receiving a roller or other stud, as a",at the end of a connecting-rod a5, which atits opposite end (see Fig. l)embraces a stud a, adjustably secured to an arm a7 of a rockshaft aserected in a stand a at one end of the machine, the said ioeleshaft, asherein shown, having secured to its upper end an arm am, represented asslotted at its outer end to receive a pin or projection, as 2, extendedoutwardly from the under side of a slide an, to which is secured by ascrew 3, or in other suitable manner, the carrier als for the strand.The slide am is adapted to be reeiprocated back and forth on thediagonal raceway al, supported in suitable manner. The cam a, the linka5, rock-shaft a8, arm am, and slide am constitute one form ofcarrier-actuating mechanism; but l do not desire to limit my inventionto the means for actuating the carrier of the precise form of mechanismherein shown.

From the description it will be understood that the carrier movesdiagonally across the frame-work of the machine. The front end of thecarrier, as best shown in Fig. 8, is herein represented as having anopen eye, as 4. lhe cross-bars a2 have vertical flanges b, which arefaced to constitute one side of guide ways for the shanks of the slidesc and (Z, the other side of the guideways being composed of plates battached by suitable bolts, as b2, to connecting-webs b3, forming Ypartsof the said cross-bars, the said shan ks straddlin g the said webs, asshown in section in Figs. 5 and G, there being two slides at each sidethe 1nachine. The slide-framesc d are grooved longitudinally at theirinner sides, as shown best in Fig. 3, to receive loosely like-shapedends, respectively, of the clamp-bars c d', the two constituting what ishereinafter termed the clamp. Each clamp-bar has upon its acting face aseries of projections 6, having grooves, all the said grooves being inline, while between the said projections are spaces. As herein shown,the said projections are attached to bars 7, secured to the clamp-barsby means of like set-screws 8, such construction being desirable, inorder that the said bars 7 may be readily detached from the clamp-barsfor the substitution of other bars having projections applied thereto atthe proper distance apart to aeccommodate the size of theV check. Thegrooves in the projections are to permit the passage of the carrierdiagonally across and through the fabric, and to also enable the strandto be drawn back as the carrier is retracted.

In practice the projections of the clampbars c and CZ are so arrangedthat the projections on cla1np-bar cl, when the two clampbars arebrought together upon the fabric, enter the spaces between theprojections on the clamp-bar e--as, for instance, referring to Fig. let,it will be supposed that the proj ections on the clamp-bard are actingon the warp-strands D, arranged in pairs to bend them down, while theproj ections on the clampbar c extended upwardly act upon the undersides of the weft-strands D', bending them upwardlythus leaving anunobstructed diagonal channel in the fabric, between which the carriermay be inserted to receive in its eye the end of a strand, as f, to betaken by the carrier through the fabric. Each clamp-bar, as hereinshown, is preferably provided with a like series of points, as 10,preferably carried by a bar l2, which is attached to each clamp-bar rooIOS

IIO

by a suitablescrew, the said points entering the spaces left in thefabric between the warp and weft strands, thus aiding in keeping thefabric in proper position or to register it so that the projections 6 ofthe clam p-bars may come correctly upon the warp and weft strands,respectively, in pushing them up and down to form the diagonal channelor passage in the fabric. The slide c rests upon and is actuated by thecam c2, fast upon the cam.- shaft A. The lower end of each slide d isslotted to embrace the lnain shaft, and each slide d has a roller orother stud, as 14,'whic`n is acted upon by a cam, as d2, also carried bythe cam-shaft. Each of the slides c and d has a pin, as shown best inFigs. 3, 5, and 6, the pins of adjacent slides receiving upon them theopposite ends of a strong spiral or other spring, as 15, the saidsprings acting on pins of adjacent slides so as to act normally to movethe slides in opposite directions to open the clamp-bars and free thefabric between them, as when the clamp is to be moved backwardly afterhaving been moved to feed the material; but these springs are notpermitted to act except at certain times, that depending upon thepositions of the cams c2 cl2. The lowermost clamp-bar c is-hereinrepresented as provided at each side with a stud or pin 16,

which is extended loosely up through a hole in the clamp-bar d', thesaid pin causing the two clamp-bars to be movedslongitudinally inunison. The lowermost clamp-bar c has depending from it (see Fig. 3) astud 17, which enters a cam-groove 18 (see Fig. 1) in a cam h, fast onthe upright shaft ax, the said cam in the rotation of the said shaftcausing the clamp-bars to be reciprocated at the proper time, and duringtheir reciprocation in one direction the clamp-bars are held together bythe slides carrying them, and when being reciprocated in the otherdirection, or backwardly, the clamp-bars are opened by the springs 15referred to.

The upperpart of the machine has a suitable bearing, as h', in which isplaced the threading device to be described, the said threading device,as herein represented, consisting, essentially, of a movable jaw h2, anda dog h3 pivoted thereon, the said movable jaw, as herein represented,forming part of an arm h5, secured to a rock-shaft h2o, another arm, ash, extended from the said rock-shaft, having attached to it a leg 717,provided with a collar hs, to which is connected a spiral spring whichsurrounds the said leg, the lower end of the spring-it beingacontractile spring-being attached to an ear hm secured to theframe-work, the said spring normally keeping the threader in elevatedposition, the threader being thrown down at the proper times to placethe end of the cane into the eye 4 of the carrier by the action againstthe lower end of the leg of the cam 71.12, (shown best in Fig. 4,) faston the cani-shaft A.

On the frame-work, just below the threader, I have erected a throat m,which, as represented n Fig 12, has av hole 181 for the passage of thecarrier als, the upper end of the throat being notched, as at 19, toconstitute the stationary member of a cutter. On the frame-work oppositethe said throat I have made a suitable guideway, as n., in which isplaced the block fn', to which is secured by a suitable screw a cuttern2. This block n has connected to it a link n3, which is joined to theupper end of a lever n, pivoted at a5 oukv a suitable stand, as n, thesaid lever, which preferably is offset, having a suitable roller orother stud, as nl, which enters the groove ng of a cam-hub a9, fast onthe shaft A.

The slide n', the link n3, lever n4, andV cam v ttf constitute one formof cutter-actuating mechanism; but I do not desire to limit my inventionto this precise form of cutter-actuating mechanism.

The frame-work of the machine, as herein shown, is provided with adelivery-beam, as o, and a take-up-beam, as p, and between the saidbeams, at each side of the clamp referred to, I have provided themachine with a pair of pressure-rolls, asF. a spool or to resemble anyusual warp-beam, receives upon it the cane fabric woven with warp andweft in usual manner, the said fabric being led between one pair ofpressure-rolls, then between the clamp-bars and between the next pair ofpressure-rolls,an d through them to the beam p, which may be of anyusual shape common to any take-upbeam, which receives upon it thematerial after the same is provided with the diagonal strands f.'

The j ournalof the take-up beam p has fast upon it a pulley p', overwhich is extended a belt p2, in turn surrounding a pulley p3 on the endof the camshaft, the said belt driving the said take-up beamfrictionally and in such manner as to enable it to take up the slack inthe fabric left after feeding the same positively forward by the clamp.The fabric having been inserted between the clamp-bars, as described,and the clamp-bars being in their farthest backward position or nearestthe beam o, are brought together upon the fabric, causing theprojections 6 of the clamp upon the Warp and weft strands alternately toraise and lower them and form the diagonal passage through the fabric.ln this condition the carrier is inserted through the said diagonalVpassage, and, arriving at the opposite yedge of the fabric, thethreader, if it be used, will be actuated to insert the pointed end ofthe strand into the eye 4 of the carrier, the threader during suchoperation moving from its position shown in Fig. 10 down to the positionshown in Figi). The cane having been inserted in the eye of the carrier,the latter is reciprocated, taking with it the end of the cane, drawingit along through the threader, which remains down and open until thecarrier nearly completes its backstroke, at which time the threader ispermitted to rise into the position shown in Fig. 10,

The beam o, made as IOO IIO

and the cutting mechanism is started to move the cutter forward againstthe strand, the cutter, owing to the shape of the groove in the cam,first impinging against the strand and holding it While the carrier completes its backward stroke sufficiently to pull the carrier off from theend of the strand, which done, the motion of the cutter is continued farenough to cut olf the strand and leave it with a preferably centralpoint, the pointed end of the strand being left projecting below thethread er. After this the clamp is moved forward by the cam h, and theprojections l0 yet being in the spaces of the checks and the projections6 yet holding the strands, the fabric 1s moved forward. The clamp havingbeen moved toward the beam p for a distance equal to the one row ofchecks, the springs l5 are permitted to operate to open the clamp-bars,and immediately thereafter the clamp-bars are moved backward to theirposition nearest the beam o, when they are again closed, as before, onthe fabric.

It Will be obvious, with the fabric the same side up, that the machinedescribed could insert the diagonal strand in butonedirection, so thatto put in the opposite diagonal strand it 1s necessary either to turnthe fabric the other side up and feed it through the machine, asdescribed, or else carry it to a second machine in which the parts aremade opposite-handed.

I claiml l. rlhe combination, with a reciprocating separable clamp toclamp the cane fabric and form a diagonal channel in the same and meansto reciprocate the clamp, of a carrier to insert a strand into the saidchannel, and means, substantially as described, to separate the clampduring its reciprocation in one di rection and to close it in itsmovement in the opposite direction, substantially as described.

2. The combination, with a clamp to clamp the cane fabric and form adiagonal channel therein, and a carrier to insert a strand in the saidpassage, of a threader, to operate substantially as described.

3. The combination, with a reciprocating clamp to clamp a cane fabricand form a diagonal passage therein, and a carrier to take a strandthrough the said passage, of a cutting device to sever the said strandto the proper length, and means, substantially as described, toreciprocate the clamp thereafter to feed the fabric during its movementin one direction, substantially as described.

4. The clamp-bars having projections to act upon the Warp and weft ot'the fabric and form a diagonal passage, combined With points to enterthe spaces of the fabric parallel to the spaces Which are being providedwith diagonal strands, the said points aiding in `positioning thefabric, substantially as described.

5. The clamp-bars to hold the fabric, as described, and the carrier,combined with the cutter, and means, substantially as described, toVmove it to clamp the strand at about the time the carrier completes itsreturn-stroke to thereby Withdraw the carrier from the strand andthereafter to cut the strand, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence ot' two subseribin g Witnesses.
